  The present invention relates to an information terminal device, and in particular, an external server (center device) that distributes a control program for home appliances, an information terminal device that executes a control program, and an information terminal device and a home appliance each communicate information. The present invention relates to a household device system that is connected in such a manner that a control program is downloaded from an external server to an information terminal device to control the operation of the household device.

  As an example of a technique for downloading a device control program from an external server and controlling a household device, an application represented by a remote control application executed by a program for remotely operating a television receiver using a mobile phone There is.

  A remote control application realized on a mobile phone uses, for example, a database storing a remote control program in an external server operated by a manufacturer of household electrical equipment. A user accesses an external server via the Internet, searches for a desired remote control application, downloads the found remote control application to a mobile terminal or the like, and executes the remote control application on the mobile terminal. Service is in practical use. Furthermore, as a remote control application, it is also proposed to set the manufacturer and model of an operated device (for example, a television receiver) to be operated, and operate the operated device by a communication method such as infrared (refer to the following patent document). 1).

JP 11-41364 A

  In the home appliance system described in Patent Document 1, the user once accesses the external server (center device) and manually designates and selects the operated device while looking at the model and the like. It is necessary to take a procedure of downloading a program for the remote control application to the storage unit of the information terminal device so that a dedicated application for operating the device functions as the operating device.

  In addition, there are many cases where there are programs of different versions even in the same type of device to be operated, and a plurality of different types of devices are generally present. For example, in a general home, there are usually about three television receivers, about three air conditioners, and about ten lighting devices. In such a situation, performing a task of selecting a desired application with one portable information terminal device possessed by a member of a family searches for an appropriate external server and identifies model devices to be operated. In many cases, it is necessary to search for an appropriate application, etc., which makes the operation cumbersome or hardly practical.

  On the other hand, if, for example, an application necessary for operating all the selected devices is held in advance in one information terminal device, the complexity of the above operation is eliminated, but a small portable device is provided only for such an application. There is a problem that the capacity of a recording medium built in or externally attached to the information terminal device must be increased. In addition, if the storage medium has a large capacity, the cost of the information portable terminal is increased, and if the latest application is always kept, the maintenance process for updating to the latest application becomes complicated. is there. Even if a large-capacity recording medium can be prepared at low cost, the complexity of selecting which application to use remains the same.

  An object of this invention is to provide the portable information terminal which can control many to-be-controlled devices easily.

  According to an aspect of the present invention, a first communication unit that transmits information for specifying a control target device to an external server, and obtains control software for the control target device from the external server; and the received control software A control unit that executes the program, a second communication unit that transmits a control command to the device to be controlled, and a reading unit that reads information unique to the device to be controlled.

  When the portable information terminal device is directed to a home-operated device to be controlled, device information can be automatically acquired from the home-operated device. In this case, since the operation directed to the household operated device that wants to control the portable information terminal device is the same as the operation performed by the remote controller that controls the remote control device toward the household device, there is no sense of incongruity for the user.

  You may have a temporary recording means to store the control program of the said household apparatus temporarily from the said external server. The temporary recording unit includes a first memory and a second memory that expands and executes a program transferred from the first memory, and the first memory holds only one program. When the one program is transferred to the second memory, the program in the first memory is deleted.

  It is preferable that a display unit is provided so that a user interface for controlling the controlled device by the control software program is displayed on the display unit. When the end of the control operation is detected, the user interface is preferably hidden and the control program is also deleted.

  The information communication terminal device as described above, wherein the second communication unit includes a plurality of communication units, and the controlled device acquired from the reading unit by a communication unit suitable for communication with the control target device The portable information terminal device may be selected based on the information.

  Also, a process for creating a means for controlling a series of controlled devices that includes a power button for turning on the power of the device to be controlled and starting with a process of reading information specific to the device to be controlled by pressing the power button It is better to start. The reading unit preferably reads information for specifying the controlled device from a character, code, or tag displayed on the controlled device.

  The reading unit may be a light sensor liquid crystal pad using a light sensor liquid crystal. The optical sensor liquid crystal pad incorporates an optical sensor on the transistor shape surface constituting the liquid crystal panel, and can recognize the multi-touch by the finger on the liquid crystal surface and the movement and shape of the touch pen.

  According to another aspect of the present invention, in the portable information terminal device, in response to a start instruction for processing related to control of the controlled device, the device information related to the controlled device is acquired from the controlled device, and the acquired device Based on the information, a control program for constructing a control interface for controlling the controlled device is acquired from an external server correspondingly holding the device information and the control program for the controlled device, and the acquired control There is provided a control method for a controlled device that executes a series of steps for constructing a control interface based on program software. When the control program is acquired, stored in the ROM and expanded in the RAM, the downloaded software is preferably automatically deleted from the ROM.

  The present invention may be a program for causing a computer to execute the above method, or a storage medium for storing the program. The program may be acquired by a transmission medium such as the Internet. Further, it may be a system including an external server, a controlled device, and the like.

  According to the present invention, it is possible to automatically identify a household device to be controlled and to download control software suitable for the device, so that various household devices can be controlled.

It is a figure which shows the example of a display of a user interface at the time of actually making the program containing the function of remote controls, such as the acquired television receiver, in the display part (a part of reading part) of a portable information terminal device.

  Hereinafter, a mobile information terminal device according to a first embodiment of the present invention and a control technology of a device using the same will be described with reference to the drawings. FIG. 1 and FIG. 2A are functional block diagrams showing a configuration example of a device control system using the information terminal device according to the present embodiment. The device control system according to the present embodiment includes one or a plurality of (only one is shown in the figure) external server (center device) A, one or a plurality of control target devices C, and a portable information terminal device. B, and these devices are configured to be communicable as shown in FIGS. 1 and 2A. A general information terminal device such as a PC may be used instead of the portable information terminal device.

  First, the external server A will be described. The external server A has a function of returning a program for executing the application based on the request (request) of the application from the portable information terminal device B.

  In the external server A, communication means for communicating with at least one portable information terminal device B, for example, communication means 1 having a wireless LAN function or a communication function using a mobile phone network, and the portable information terminal device B are legitimate. For example, a program storage unit 7 for recording a program, and a program selection unit 5 for selecting a program for a controlled device identified by the identification unit 3.

  The identification means 3 of the external server A is connected from information such as individual information (ID, for example, telephone number) of the connected personal digital assistant device B or user information specifying a user registered in this service. It is determined based on whether or not the registered ID is on the list whether or not the portable information terminal device B that is being used is a portable information terminal device that is a service target.

  In the case of a device that is not a service target, the mobile information terminal device A is notified that it is out of the service target by processing such as returning an error code via the communication means 1. Viewing this notification allows the user to terminate the connection.

  When the identification unit 3 confirms the connection from the portable information terminal device to be serviced based on the terminal ID or the like, the service program determination process is performed. That is, when the portable information terminal device B transmits at least information on the device to be controlled, such as model number information, to the external server A together with the terminal ID, the identification unit 3 determines that the portable information terminal device B is a device to be serviced. The program selection means 5 provided in the external server holds a correspondence table of, for example, model numbers and service programs for specifying controlled devices, and selects service program IDs from the model numbers based on the correspondence tables. To do. From this ID, a desired service program is selected from a number of service programs stored in the program recording means 7. The selected program is returned to the portable information terminal device B via the communication means 1.

  In this way, the communication unit 1 transmits at least one of the program from the program selection unit 5 or the error code from the identification unit 3 to the portable information terminal device B. You may make it also send the success code (report) when the identification means 3 succeeds in identification to the portable information terminal device B via the communication means 1. FIG. In this case, the communication unit 1 may transmit either the success code and the program or the failure code (error code) to the portable information terminal device B.

  The controlled device (household device) C is, for example, a general television receiving device, a storage / reproducing device, or an air conditioner. Is configured to receive a command relating to an operation or the like from the computer and execute processing according to the command. The communication means may perform wired communication or wireless communication. Uses commonly used wireless standards such as IEEE 802.11a / b / g and Bluetooth (trade name), sends commands via TCP / IP protocol, or uses infrared (remote control device for television receiver) As well as sending instructions to operate the equipment. As described above, there are few restrictions on the controlled device (household device) C, and when the communication means is not provided, the communication means may be provided externally, so that it is applicable to most electronic devices and the like. be able to.

  Next, a portable information communication terminal device will be described. The portable information communication terminal device B performs information communication between the external server A and the interface unit D including a reading unit that acquires control target device information related to a control target device (home device) that is a control target. The first communication means 11 and the interface unit D may be included, but are used to execute a program downloaded from the external server A, and control unit (CPU) 17 / display unit for controlling the whole (Display) 21 / Input / output unit 27, ROM 23 for storing programs, RAM 25 for reading out and developing programs and performing high-speed processing, and home appliances to be controlled Two communication means 15.

  FIG. 3 is a diagram illustrating an overall configuration example of a device control system using the portable information terminal device B according to the present embodiment. An external server group (A) composed of a large number of external servers 0 to n and a large number of household devices 1 to m (C) are configured to be connectable via the portable information terminal device B. In this system configuration, communication is performed by selecting one of the external servers 0 to n from the information on the household device C. For example, when the model information obtained from the household device 1 includes the address (URL, etc.) of the external server 1, the program can be downloaded directly from the external server 1. When the model information obtained from the home device 1 does not include the address information of the external server 1, the model information of the home device 1 can be transmitted to, for example, the external server 0 and the program can be downloaded ( An external server (which is known to be able to hold or acquire a program) is requested to search the external server 0, and the address of the external server is received. Next, a desired program is downloaded to the portable information terminal device B using the received address of the external server (in this case, the external server 1).

  Next, a method for identifying the type (model name) of the household device C using the input / output unit 27 of the portable information terminal device B will be described with reference to FIG. 2C.

  FIG. 2C (a) is an example in which the interface unit D including the reading means includes a barcode reader. It is a figure which shows the example in case the barcode which shows the kind (model name) is attached | subjected to the surface of the household apparatus C, and the barcode reader is contained in the reading means of the portable information terminal device B. The type (model name) of the household device C that is the barcode reading result of the portable information terminal device C by activating the barcode reader functioning as the reading means and causing the portable information terminal device B to scan the barcode. Can be recognized. The display part of the model name may be read instead of the barcode. In the case of a barcode, a decoder that decodes the barcode is used. However, the model name displayed in text may be imported as an image, and the model name may be acquired from the image using OCR.

  Alternatively, as shown in FIG. 2C (b), the portable information terminal device C is provided with a camera as an interface unit D including a reading means, and the type (model name) is provided on the surface of the household device C by the camera. It is also possible to recognize the type (model name) of the household device C by reading the character or code that it represents.

  Further, for example, a tag such as an IC tag for storing the type (model name) is provided in the household device C, while a tag reader such as an IC tag reader is provided as an interface unit D including reading means in the portable information terminal device C. If provided, the contents of this tag can be read to know the model name.

  In addition to the above, there is also a method using authentication such as Bluetooth as the interface unit D including the reading means. When using a Bluetooth device for the first time, an operation called pairing is performed in order to specify a connection partner. If the home device (operation target device) C is in a searchable state, pairing can be performed by performing a search operation on the portable information communication terminal side. By collecting and accumulating device information of the partner device (operation target candidate) during this pairing operation, it is possible to select the control target device from the list of devices that can be connected via Bluetooth the next time. It is. The method described above is an example of a method for identifying the type and model name of a household device using a portable information terminal device, and any other known method can be used as long as necessary information can be acquired. May be.

  The first communication means 11 for communicating information with the external server A of the portable information terminal device is automatically activated when a power button or the like is pressed toward the home device. The type (model name) of the household device C is acquired by the reading means, and information is exchanged with the household device to be controlled by starting the program based on the acquired type (model name) of the household device C. You may make it control by the 2nd communication means 15 which performs communication. In this way, if a portable information terminal having a remote control function is pointed at various household devices and a start button for control or the like (or a power button may be used) is pressed, the user is not conscious of the home. Equipment can be controlled.

  Next, state transition of the portable information terminal device will be described with reference to FIG. As shown in FIG. 5, the portable information terminal device is in a state of M2 / stop processing M2 / end processing M10-11 / standby M3 / target device identification processing M5 / downloading M6-7 / program execution M8 And transition between those states.

  First, when the power is turned on, it becomes M2 during the startup process. As the activation process, various devices are initialized. When all the startup processes are completed, the standby state M3 is entered. For example, the process proceeds to the target device identification process M5 by a user operation. Here, as described above, the home device is identified, and the home device information is connected to the program download source (external server). If necessary, authentication is performed and a program for the household device is downloaded from an external server (M6-7). When the download of the program is completed, the portable information terminal device executes the downloaded program (M8). When the program is terminated, it returns to the waiting state and waits for the next user input (M3). When the power-off operation of the portable information terminal device is performed, a termination process is in progress (M10 to 11), and after the termination process of each device is performed, the power is turned off.

  Next, detailed contents of the processing according to the present embodiment will be described with reference to the flowchart of FIG. FIG. 4A is a flowchart showing a process flow in the portable information terminal. FIG. 4B is a flowchart showing the flow of processing in the external server. FIG. 4C is a diagram showing details of a flow of processing related to reading out of processing in the portable information terminal shown in FIG. 4A. The description will be made with reference to FIGS. 1 and 2 as appropriate.

  As shown in FIG. 4A, first, when processing is started in portable information terminal device B (step S1: start), initialization of devices in each functional unit indicated by reference numeral B in FIG. 2A is performed as necessary. In step S3, a standby screen display such as a menu screen or a standby screen is displayed on the display unit 21. Here, when a processing start button (a part of the input / output unit 27) related to the control of the household device according to the present embodiment is pressed (yes: for example, a remote control application) is started. If the start button is not pressed (No) and the end button is pressed (step S10: yes), the process ends in step S11. If the end button is not pressed (No), the process returns to step S3.

  In step S5, model identification processing is performed by the reading unit D and the like regarding household devices that are controlled devices. Next, in step S <b> 6, a program (software) for constructing a control interface for controlling household devices is downloaded to the ROM 23. When the software downloaded to the ROM 23 in step S7 is expanded in the RAM 25, the downloaded software is deleted from the ROM in step S7. In this case, the contents of the software may be deleted, leaving only the software identification number. The contents of the software can be restored in the ROM at any time by the remaining identification number. In step S8, the software is executed by the program developed in the RAM, and when the software processing is completed (step S9), the screen returns to the standby screen in step S3.

As shown in FIG. 4B, in the external server, first, from the portable information processing terminal, when receiving the terminal ID and the reading result of FIG. 2C such as the model number of the household device that is the target operated device, step S5 The mobile information processing terminal is identified, that is, whether or not the mobile information processing terminal is a terminal registered in the external server. If the portable information processing terminal is a terminal registered in the external server (yes), the process proceeds to step S24. If no, the process proceeds to step S23, and an error code is returned to the portable information processing terminal.
In step S24, the program requested by the portable information processing terminal is selected, the requested program is returned to the portable information processing terminal in step S25, and the process ends in step S26. Through these processes, a program requested by the portable information processing terminal can be passed.

  As shown in FIG. 4C, when the mobile information processing terminal starts processing in the reading mode (step S31: start), the portable information processing terminal transitions to the reading mode in step S32, and as shown in FIG. 2C in step S33. When an operation for starting data input is detected (Yes), the process proceeds to step S34, and data such as a device ID is read from the control target device, for example, from a barcode. In step S35, processing such as data decoding is performed. In step S36, the URL indicating the location of the program and the terminal ID for identifying the terminal are transmitted to the external server. Thereafter, the process shown in FIG. 4A continues.

As described above, the processing according to the present embodiment can be automatically executed by the following series of flows.
1) When the portable information terminal device is directed to a household operated device to be controlled, the device information can be automatically acquired from the household operated device. In this case, since the operation directed to the household operated device that wants to control the portable information terminal device is the same as the operation performed by the remote controller that controls the remote control device toward the household device, there is no sense of incongruity for the user.
2) An external server is automatically connected based on the device information automatically acquired in the process 1) above, and a control program suitable for controlling the home operation device 1) is downloaded.
3) The downloaded program is immediately transferred from the ROM to the RAM and executed, and the user interface of the remote control application is displayed on the display unit.
4) The user can operate with the user interface while keeping the portable information terminal facing the household device.
5) Once the operation is finished, the user interface is hidden and the program is deleted, and if it is directed to another household device, the other household device can be operated by the same processing.

  Here, if the direction of the portable information terminal device is substantially the same between device information acquisition (when reading) and device control, that is, if the reading direction and the control signal emission direction are substantially the same, the user Therefore, since processing is performed on the back side without being aware of acquisition processing of programs and the like, it is possible to concentrate on device control.

  Through the above processing, an operation interface for the operated device can be generated in the portable information terminal device.

  FIG. 6 is an external view of the portable information terminal device B. A button indicating whether or not to start reading a program is displayed on the touch panel type display unit 21 on the interface unit D including the reading unit, and further on the casing. It is a figure which shows the state in which the antenna 105, the power button 101, and the end button 103 are provided. Here, when the read start button 107 is pressed, the program is read and the processing of FIG. 4A is executed. This difference, for example, the first communication means 11 is cut off and the program is started. When there are a plurality of second communication means 15, the device to be initialized is determined using the used device information included in the program. The device used in the second communication unit 15 may be the device used in the first communication unit 11. While the program is being executed, the state can be notified to the user by displaying the state on the display unit 21.

  FIG. 7 shows a display example of a user interface when a program including a function of a remote controller such as the acquired television receiver is actually executed on the display unit (part of the reading unit D) of the portable information terminal device. FIG. Based on the acquired program, a button is displayed on the display unit 21, and a function required for each button (for example, in the remote control function for the television receiver shown in FIG. In addition, the volume, channel up / down buttons, etc. are allocated and displayed as commands, specifically, buttons (1 to 12) 111 and volume up / down buttons 113 used for channel operation. Are displayed as so-called software buttons, and a power button 101 and an end button 103 are provided as so-called hardware buttons on the casing avoiding the display unit 21. The hardware buttons are provided on the electronic device. It is preferable that the button has a high commonality that is generally required.

  The user interface displayed on the display unit 21 is the same as the method realized in, for example, Patent Document 1 described above. One of the features of this embodiment is that the program acquired from the external server is first stored in the ROM, but when the program is executed, it is expanded in the RAM and the program is deleted from the ROM. Note that whether or not to delete may be selected by a user operation.

  FIG. 7B is a diagram illustrating an example of downloading an operation program for an air conditioner that is another operated device. As shown in FIG. 7B, the display unit 21 includes a current set temperature display field 121, a function selection button 123 such as cooling, heating, dehumidification, and air blowing, and a set temperature adjustment button 125. And a power button 101 and an end button 103 are provided on the case where the display unit 21 is avoided.

  As described above, a user interface suitable for the operation of a desired operated device based on the downloaded program is displayed on the display unit of the portable information terminal device, thereby enabling a remote control operation suitable for each operated device. A user interface including software buttons can be formed, and the operated device can be appropriately operated.

  Note that the second communication means 15 (FIG. 2A) may be initialized based on the activated program. This will be described by taking as an example the case where the household device that is the operated device is a television receiver. As command control means from the operating device (remote control device) for the television receiver, there are generally LAN / infrared / Bluetooth or the like depending on the communication medium. Depending on such instruction control means in the television receiver, the portable information terminal device is based on the device information of the household device that is the operated device (which external control means is supported). It is also possible to automatically select an appropriate external control means. When there are a plurality of options, the user may be presented with choices and selected from them. In addition, since LAN / Bluetooth communicates in both directions, a registration procedure is required between the home device and the portable information terminal device (this registration procedure is a general procedure. (The explanation is omitted, but it is a procedure based on negotiation.) In addition, when infrared rays are used, it is only necessary to transmit a command that matches the communication protocol because it is one-way from the portable information terminal device to the controlled device (from the portable information terminal device to the household device). There is no need for negotiation.

  As described above, the external server selects a program for home appliances based on information obtained from the connected portable information communication terminal device, and passes through a communication network connected to the portable information communication terminal device. The selected program is transmitted.

  In addition, for example, when the information displayed at a predetermined position on the surface of the home device is extracted from the image read by the image input unit (camera, etc.), for example, as shown in FIG. The software to be downloaded is selected based on the extracted model information, but if there are multiple selection targets, a list of the multiple targets is extracted once and any software is selected for the user. It is sufficient to display a menu that can be selected by the user after confirming whether to use and to select one from the menu display. With such processing, when executing the downloaded software, it is possible to establish a communication path with the target device and perform negotiation. You can also include a program that displays the status of the downloaded application. If it does in this way, according to the request | requirement of a portable information terminal device, the state (temperature in a store | warehouse | chamber, current power consumption, etc.) of a refrigerator can also be displayed on a screen.

  In this embodiment, when either the power button 101 or the end button 103 is pressed, the program in the RAM is erased and no program exists in the ROM, so that the so-called initial state is restored. of course. The program may be configured to return to the ROM, or the number of programs that can be stored in the ROM is limited, and the stored program is sequentially updated as new programs are acquired. good.

  As described above, according to the device control system including the portable information terminal device according to the present embodiment, the home device to be controlled is automatically identified, and the latest control software suitable for the identified device is automatically detected.
